"THIS" is a biggie for those with the 3500 rear air when unhitching. If you are slow about unhitching the rear air system will start trying to re level and give you a big startle when un hitching. I read on another forum of a guy thinking it was all the fault of his new to him B&W hitch.
So here is the way to unhitch and hitch if you so choose.
When backed into the spot where you want to unhitch go into "Settings" then select "Suspension" then select "Tire Jack Mode". This will keep the rear from moving while unhooking and hooking. I touch no controls after unhooking then the system goes back to Alt Ride Mode as I had it set. I leave mine in Alt ALL the time.
Hope this helps with someones frustration!
